IT Service Management Lifecycle
� IT Infrastructure Library (ITIL) is the most widely accepted approach to IT Service Sanagement. It provides a best-practice framework for identifying, planning, delivering and supporting IT services to the business.

Definition of Service Operation
� IT InfrastructureAll of the hardware, software, networks, facilities, etc., that are required to Develop, Test, deliver, Monitor, Control or support IT Services. The term IT Infrastructure includes all of the Information Technology but not the associated people, Processes and documentation.
Advanced Aspects of IT-Infrastructure in Healthcare 2012
� Service OperationService Operation is the phase in the IT Service Management Lifecycle that is responsible for ‘business-as-usual’ activities.
Service Operation is where the value is actually delivered.
Source: ITIL V36
Main Goals of Service Operation
� achieving effectiveness and efficiency in the delivery and support of services
� ensure value for the customer and the service provider
� maintain stability in Service Operations, therefore allowing for changes in design, scale, scope and service levels
� providing methods and tools for use in the two major control
Advanced Aspects of IT-Infrastructure in Healthcare 2012
� providing methods and tools for use in the two major control perspectives:� reactive� proactive
� providing knowledge to make better decisions in areas such as managing the availability of services, controlling demand, optimizing capacity utilization, scheduling of operations and fixing problems

Q & A6
Conclusion -> IT as a Service5
Definition
� A service is a collection of applications and capabilities that provides value to a customer� Typically involves a number of individual servers, each supporting one or more
applications� Services are complex systems, often the needs of the system is greater than
the sum of the need of individual servers
Advanced Aspects of IT-Infrastructure in Healthcare 2012 9
Challenges and Cost Factors in Today´s Enterprises
� Slow service delivery� Bringing a new service to life involves multiple teams� Poor coordination can mean service delivery times of 90+ days
� Lack of transparency� Poor visibility into the operations of business services makes it hard to
guarantee service levels and correctly interpret anomalies
� Too little automation
Advanced Aspects of IT-Infrastructure in Healthcare 2012
� Expensive and error prone manual workflows can lead to business service disruptions

Standardize Infrastructure Delivery
� Return cost visibility to the system by delivering standardized infrastructure components
� Infrastructure specification + Service-level agreement� Account for the cost of providing the requested level of service� Clearly differentiate between service levels and server capabilities by exposing
cost� Provide an array of different options via catalog
� Standard components and standard SLA´s made available to the business
Advanced Aspects of IT-Infrastructure in Healthcare 2012 17
� Standard components and standard SLA´s made available to the business with visible cost structure� Simplify planning on both sides of the transaction

Without Virtualization
Advanced Aspects of IT-Infrastructure in Healthcare 2012 21
� Provides hardware virtualization that presents a complete x86 platform to the virtual machine
� Allows multiple applications to run in isolation within virtual machines on the same physical machine
� Virtualization provides direct access to the hardware resources to give you much greater performance than software emulation
Virtualization Increases Hardware Utilization
